',o all whom it may concern:

Re it lniown that. l; fs-.ooe lisiainii, :i citizen ol? the United States, and resident oi' the borough ont ll/l'anhattnn, city of New York, in die county of New York State of New York, have invented eertnin new and useful lniproreinents in Typed', r ng Machines, of which the following is a, speeilication. v

lilydnrention relates to typeivriting ine chilies and more particularly to stop devices for arresting the platen at predetermined points in its rotation., tho mechanism Abeing,` devised more especially tor use in prepa-ring condensed record billing work. j

The inain object of the invention is to provide simple and ctiicient nie-ans olf the character specified. i

. further object of the invention-is to provide stop devices which may he readily chine embodying my invention.

applied to existingl forms of typen-riting machines Without modifying., or materially modifying, the structural features of said In chilies as they now exist.

To the above and other ends which will hereinafter appear, my invention consists in the features oi? construction nrranggcinents olf parts and combinations of devices to he hereinafter desorilied and particularly pointed out in the appended claims.

ln the accompanying drawings N vherein like reference characters indicate corresponde` ing, parts in the Various vier-fs, Figure l is an end ele ation and in section, on an enlarged scale. of part of a typewriting ma an enlarged plan View of the seme, showing in addition the parts which are sectioned away in l. 3 is an enlare'edv detail sectional View taken transversely through the sitos` carrying har and chain and showing' the chain and stop. Fig. el; is an enla-rged detail sectional 1view taken .transversely through the-stop oarryinff bar and showing; the adjustable stop carried thereby. Fig. 5 is an enlarged fragmentarycend elevation of some of the parts shown in Fig.2, the linger `wheel heilig` sectioned away in 5. Fig. 6 is an enlarged vdetail sec tional View ot the clutch and some oi the part:'a"ssoeiated 'therewith7 the section being taken longitudinally of the platen slialit.

Figs. 7 and S are enlarged detail perspective Viewsoi the engaging ineinlaers o the clutch. Fig. 9 is anenlarged detail sectional View of the reersprocliet wheels and the adjustable ture of said machine.

`'lhe topv plate l snifiports standards 2 to which fixed guide rails 3 are secured by screws The rails ES are oppositely grooved and vreceive anti-friction halls-or rollers 5 which' also run in opposite grooves 6 formed in a rear cross bar or 'traverse har 7 constituting part of the paper carriage. lrojeoting forwardly from the heck bar 'Y are end bars 8, these several bars .termin j in the main the platen frame or earring cylindiez'il rotative platen 9 is secured toe platen shaft l0 by a set screw ll which enters a threaded hole in thehub of a right-hand platen heed l2 and hears against the platen shai'ft.- The platen shaft 'extends through and is journaled in bearing openings in the end plates S and is provided at its ends with finger Wheels 13 and 14 secured to .the platen shaft in the usual manner. rlthe left-hand pleten head is formed with line spacing Aratchet teet 15 thereon with which a springpressed roller detent 16 cooperates. rl.- line spacing pawl 17 is pivoted to end carried by an arm C and co-acts with the line spacingr Wheel under the control of e linger piece 19 to eect a step-by-step line spacing movement of the platen. The righbhand end plate 8 of the carriage is formed With an upwardly. eX- tending arm 20 provided 'with a finger piece 2l by which the carriage may he -moved to the right and by which it niay'he controlled when 'released from its spring drum for rapid increment toward the left. The parts thusY :fer described are of the usual construction embodied in the Monarch typewriter and a further description thereof 1s deemed unnecessary.

'llie righhhand end of Ithe platen shaft A l) Where it4 extendsloeyond the platen freine is forxnedwith a spline ,groove 22 1n 'which ll is a fragmentary a spline nieves o). rEhe spline 23 is secured 'to a clutch ineinber 24 which surA rounds the platen shajt't and is provided with a peripheral grooif'e The clutch uieinber coniprises an inwardly extendingv vided with outwardly extending teeth 32' which are adapted to coperate with the clutch tooth 27 on the member 24 and which -are preferably thirty-three in number corresponding to the number of teeth ol" the line spacing ratchet wheel. lhe purpose of this is:- 'to enable the clutch sections to be brought into proper position" to engage no matter what position the platen may be ar rested in. The annular flange 3l surrounds the coiled spring and is itself surrounded by the annular flange 26 on 'the clutch section fill. The clutch member 30 is provided with an inwardly extending hnb which loosely niounted on the platen shaft and to said hub is rigidly'connected a'sprocket wheel Srl. rlhis :nay be secured by a drive fit or by set screw or otherwise.

Frein an inspect-ion ot 2 and 5 it will be observed that a bracket arm is'secured to the right-hand end Iplate of the platen traine by screws 56. A lever 37 is pivoted, on a shouldin'ed headed screw 38, to the outer end ot the bracket. rlhe form of this lever is best shown in Fig. 5 troni which it will be seen that it is provided with a se1ni cylindrical portion 39 contained within the circuniferential groove in the clutch section 24. 'l his lever provided with studs or rounded eiilargcnnnns l0 .and ell which are situated upon opposite sides of the axis ot the 'platen and are ot' a thickness or diameter corresponding substantially to the width ot the groove 25. 'the lever is prolonged vat the upper portion theeoi: so as to provide i forwardly extending' linger piece -l2 by which it may be turned on its pivot Yto shit't the clutch section Ell into and ont ot cnjufatgjcnient with the companion clutch sectioil 30. lealf spring e2 is secured by screws L12"' to thi` 'ightfhand end plate of the carriage and tends beneath the lever 37. Two depressions or notches sli. are torn'ied in this spring; for engagement with thc. lev .-r in either or the two positions to which it may be shifted; that is to say, in vthe position where :in engagement is effected between the two clutch members or to the sca-57e position where the Yclutch members are disn fffiri'asred. The purpose oit this spring is to hold the hand-lever and the parts controlled thereby against accidental displacement so as to maintain the clutch inenil ers either in or out ol engagement, dependingr on the position to which the level )This moved, but

l) it desired sonicy other lmlding` iueans may he employed. l'hen the lever is in engage nient with the inner notch 2 the pressure ot the spring tim is sutlicient to overcome the tension of the spring 29, the purpose of the latter spring` beinel1 inore particularly to assure disengafj'enicnt between the clutch niemplate of the carrie lor the platen shaft and which is usually eniployedlto talle the endwise thrust ot the platen in the iilonarch machine. r

An endless oand, llexihle stop carrier, or sprocket chain 43 cooperates with. the sprocket wheel i and also coperates with a. sprocket wheel #le pivot-ed or join'naled on an eccentric or eccentric bushing 45. rhe eccentric e5 is provided with a hub -lti (see Figf) which bears at its inner end against the right-hand end plate 8 or" the platen traine or carriage. A. headed screw 47 passes horizontally through the eccentric and hub and engages at its threaded end in a threaded opening in the right-hand end plate 8, the head ot' the screw overlapping the sprocket wheel 114 and retaining it in position on the eccentric 45, but without interfering with its tree and independent rotation. The hub of the eccentric is provided with a series oit capstan openings 4S for use ot' a Spanner wrench, pin or other suitable tool by which the eccentric ay be turned on the screw JJ in order to adjust it and thus talle up any slack that tl'iere inay be in the endless band or chain 13. A set screw 49 extends through a threaded opening' in the hub of the eccentric and bears at its inner end l .gcgainst the s brew 4:7 to hold the eccentric in its adj usted position. A stop :30 as shown in F i gs. l. andv I?, is connected to the chr-.in ll--S in any suitable manner. ln present instance this stop is shown as substantially til-shaped in cross section and connected to the chain hy pivots 5l which unite adjacent. links ot `the chain. The irl-shaped form ogt'the stop 5G l enables it to surround and slide along a stop bers when tne ting-rer piece #l0 is inoved to' ot. the journal bearing in the rightfhand end form of carrviiw su) )orting or OuidinU bar 52 which u b x D b is secured at its ends to the platen frame r wardly from the upwardly'projecting arm' of the carriage; The other end of the bar 52 secured by a screw 55 to a bracket 56 which in turn is secured Vto the Acarriage by a screw 57. F rom an inspection of Fig. l it will be seen that'the'bar 52 has-a portion thereof which vis straight and extends parallel with the chain as the latter extends from one sprocket wheel ,to the other,-and that the rear end portion of the bar is curved downwardly so as to follow the curvature of the chain as it passes around the rear sprocket wheel. T he bar carries a fixed stop which is in the nature of a headd screw. An adjustable stop 59 surrounds stop bar on three sides (see Fig. et) and has a threaded opening for the reception of a binding screw 60 provided` Witha knurled head 61- by which the stop Vmay be secured in any position along the stop bar. to which.

said stop may be adjusted. c A p1n-62 eX- tends .through the innenwall of the stop and enters in' a groove 63 which extends longitudinally of the bar throughout' or substantially throughout the length thereof. This pin prevents the adjustable stop 59 from becoming detached Orbeing removed from the stop bar even when the binding screw 60 is released,

a screw so as to permit ready detachment of the stop when desired. T he stop bar isV preferably provided with a scale or indices. the distance between thc scale marks corresponding to a tooth space movement of the line. spacing ratchet wheel and platen as.

will hereinafter more clearly appear.' It will bc observed that in the present instance scale extends to forty-two which is nine spaces more than that required to effect a full revolution of the platen, it being presumed that there are thirty-three teeth of the line spacing ratchet wheel in the present instance. The purpose of this arrangement will hereinafter-more clearly appear.

ln the use of the machine for condensed record billing work 4the finger piece 42 is moved to the left to effect the clutch members.l The platen is then turned backwardly by either of the finger Ywheels 13 or 14 until the chain stop 50 e11- gages the fixed stop 58. An invoice or bill sheet is then introduced into the machine and the platen is rotated forwardly until it is in a positin to receive the first line of writing at, say, the date line thereon. During this .forward rotation of the platen 'a backward rcctilinear movement of takes place along the stop bar 5l., If, for instance, Lit required arotation of the platen graduation 25 time turning independently of but the pin 62 may be made in the i an engagement of the chain stop 50' equivalent to twenty-five teeth othe line spacing wheel to bring the bill to the proper position to receive the first line of writing. then the chain stop would he mowed to the on the stop bar. The adjustable stop 59 should then be adjusted to contact with the chain stop 50 and the screw should then be turned to secure the adjustable stop in this position. ,The platenshould then be given a reverse or backward rotation by either of the finger wheels 13 or 14 until it is arrested by the engagement of the front face of' the stop 50 with the fixed stop 58. The carbon and record sheetmay then be introduced into the machine, the record sheet being next to the platen and the ca rbonsheet being interposed between the in- .oite and record sheets'. The platen may then be turned forwardly by either of the finger wheels 13 or 14 until it is arrested by the engagement ot' the rear face of the stop 50 with the adjustable stop 59. The finger piece 42 should then be moved to the right to release the clutch and the operator may proceed with the writing, the p aten at this the stops, chain and sprocket wheels. After the bill has been completed the operator may line space twice -in order to provide for the -proper'spacing between the last line of the copy of the invoice j ust completed ou the record sheet and the first line of the next manifold copy of the invoice to be written. The finger piece 42 should then be moved to the left to effect an engagement of the clutch members andthe platen should be rotated rearwardly bv means of either of the finger wheels 13 uand 14 until the stop 50 has been brought into engagement with the stop 58 and the platen 1s arrested. The invoice sheet may then be removed without disturbing the carbon and record sheets and a new invoice sheet maybe introduced into the machine. The platen should then be turned orwardlv until it is arrested by the contact of the chain. stop 5() with'the adjustable stop 59. The clutch' should then be released and the writing proceeded with as before. In

lio

this manner carbon copies of successive billsl or. lnvoices may be made upon a condensed record sheet so that a large number of copies of different 'bills or other matter may be made in condensed form or close. arrangement on a. single record sheet.' 1

It will be observed that theconstruction is such that the stops enable the platen to 'be turned more or less than a full revolution so that the device is capable of' handling hill heads or invoice 'sheets of widely diii'erent characters;

from very short printed heads` to very long printed heads, and in which it mayV be. necessary in some 4instances to turn the platen through more than a complete revolution in that is to say,. bills varying order to brinr the first line of writing on the invoice or bill sheet to theprinting line.

Various modiiications in the structure may be made 'Without departing from the spirit of my invention.

In Fig. 11 I have shown another form of construction in which the stop bar 52a is straight throughout its entire length so that the chain stop 50 will have only a rectilinear movement back and forth. In this form of construction the chain stop is not carried by the bar 52l but runs on or over a separate bar 64e arranged parallel with the ing arranged onvtlie outer'side of the stop bar as in the construction shown in Fig. l

is arranged on thetop side of bar 52a-where it may be seen' more readily by the operator. It Will also be observed that in the form of construction shown in Fig. ll the relative adjustment between the fixed stop 5S on the stop bar and the adjustable stop 59a does not enable the platen to turn for more than a complete rrotation when the chain` `stop is operatively connected to the platen,

the greatest range of movement of the chain stop corresponding to thirtytivo spaces, slightly less than that necessary to permit a complete rotation of the platen. How# ever, this extent of movement Will be found suflicient in most cases.

lYhile I have describedone method of using my devices and forsetting them for condensed record work, it should be under-- stood that the Work may be performed in a dill'erent manner.

In a front-strike or visible Writing machine it may be necessary or desirable at times to arrest. the platen during` its backward rotation only. This may be done by omitting or removing the stop 59, in which case the operator will note visually when the proper point on the invoice sheet has been brought to the printing line and then hey-Will release the clutch. the movable stop will be held frictionally in the positions to which they have been moved and when the bill is coiripleted, theplaten li'ne spaced twice and the clutch engaged,

tion is simple in operation, and positive and reliable in use.

It will be observed that the platen, by means of its shaft and hand-Wheels, is normally adapted to be rotated freely in either direction, that is, baelrwardly or forwardly; that the sprocket Wheels or band-Wheels and l chain or band are adapted to be connected with and disconnected from said platen at will by t-lie operation'of the clutch menibers; that when the platen is rotated in either direction, and the chain or band Wheels are connected therewith, the latter Moreover, the scale instead ot' bei are caused to be rotated by the platen (or by the platen shaft which is practically the same thing) and the movable stop controlled by the chain or band is caused lto move si.- multaneously withv the platen, and in unison therewith, and Wlien`said movable stop has been carried to the point Where it engages with leither of the relatively fixed stops, it, together Wit-li its cooperating stop, causes the chain or band, the band Wheels, platen shaft, and platen all to be arrested; that thereupon the band Wheels and band and movable stop may be disconnected from the platen by a reverse 'operation of the clutch, and that thereafterthe platen may be freely rotated in either direction independently of the stop or arresting mechanism.

What I claim as new and desire to secure by Letters Patent is 1. In a typewriting machine, the combination of a rotative platen, stops for arresting said platen, a chain for moving certain o said stops, and means for enabling,-- the platen to rotate independently of said stops.
